First of all in your second timeline(Future Trunks's timeline) Goku killed Mecha Frieza and King Cold then died from the heart virus. Everything else I changed I bolded. I relabeled your main timeline to timeline 1 and Cell's timeline to timeline 3 just to make it easier.Sadako wrote:Ok, so the question is a bit more complex than the Subject says. Basically I've always wondered what fully happened when Trunks returned the 2nd time in the first alternate timeline.
To make it easier, here's my basic rundown of the timelines with the gap I'm looking to fill.
CELL TIMELINE (Timeline #3): Goku kills Freeza/King Cold -> Goku dies of Heart Condition -> Z Fighters killed by Androids -> Future Gohan killed by Androids -> Future Trunks returns to the past -> Future Trunks kills Freeza/King Cold and gives Goku heart medicine -> Future Trunks returns to the future -> 2 years later Future Trunks goes back to check on Goku -> XXXXXXXXXX -> Future Trunks returns to the future and kills the Androids -> 2 years later Cell kills Future Trunks and goes to the past (Timeline #3)
FUTURE TRUNKS TIMELINE (Timeline #2) Future Trunks kills Freeza/King Cold and gives Goku heart medicine -> 3 years later Future Trunks returns to this timeline -> Future Trunks finds the Z Fighters fighting #19/#20 -> Goku retires due to heart condition and Vegeta kills #19 -> #20 runs back to the lab and activates #17/#18 who in turn kill #20 -> #16/#17/#18 defeat Vegeta and the Z Fighters and then go after Goku -> XXXXXXXXXX -> Future Trunks returns to the Future (Kills the androids/Gets killed by Cell)
CURRENT TIMELINE (Timeline #1) Future Trunks kills Freeza/King Cold and gives Goku heart medicine -> 3 years later Future Trunks returns to this timeline -> Future Trunks finds the Z Fighters fighting #19/#20 -> Goku retires due to heart condition and Vegeta kills #19 -> #20 runs back to the lab and activates #17/#18 who in turn kill #20 -> #16/#17/#18 defeat Vegeta and the Z Fighters and then go after Goku -> Wacky Insanity involving Cell from Timeline #1 occurs -> Future Trunks returns to the Future (Kills the Androids/Kills Cell)
Obviously the XXXXXXXXXX is the gap I'm looking to fill. I don't know if it's covered in any of the guidebooks.
FUTURE TRUNKS TIMELINE (Timeline #2) Goku kills Freeza/King Cold-> Goku dies due to heart condition-> 3 years from Mecha Frieza's death on May 12 C17 and C18 appear and begin killing all the Z Fighters except Gohan and of course Trunks-> Several years pass in which Gohan trains Trunks-> C17 and C18 kill Gohan-> Trunks goes to main timeline to warn them and give antidote-> Trunks returns and trains for 3 years then goes back to main timeline -> Future Trunks returns to the Future (Kills the androids and Cell)
For Cell's timeline(timeline 3) everything should be the same as what happened in Future Trunks's timeline(timeline 2) up till the point where the time machine was completed. After that Trunks uses a shutdown controller to kill C17 and C18. Then Cell kills Future Trunks and steals his time machine just before Future Trunks was going to use it. And of course you know how the main timeline goes...
Timeline 4 is the one where Future Trunks went to from Cell's timeline(timeline 3). Since Cell's timeline(timeline 3) went the same as Future Trunks's timeline(timeline 2) up till the point of the time machine being completed that means timeline 4 is the same as the main timeline up till the Cell Games, where Future Trunks is absent because he was killed by Cell in Cell's timeline(timeline 3).
Everything I wrote above coincides with the diagram from Daiz 7 below.
